The paper deals with the drive options of mechanical presses and their influence on energy efficiency. Although the main focus is on energy efficiency, we also emphasize design and operational issues. The press machine is divided into two separate sections – the machine side and the drive side. The machine side and its efficiency is described using an energy balance formula. We quantify the energy balance for an 80 MN forging press. We describe eight different types of drives from a typical drive with a flywheel to direct drive and their combinations. We describe individual losses and efficiencies for components of the drive side.
